Laser diffraction measures the geometrical dimensions of a particle using laser diffraction patterns. First, a laser is fired through a focusing lens at a sample powder or liquid. Next, the light waves scatter and form a pattern after hitting the focal point, where a sensor measures the light’s intensity from the pattern’s center. An algorithm then determines the size of the particles examined by the laser, allowing experts to calculate the sample’s particle size distribution. The information provided allows ATS’ chemical analysis division to determine if the formulated powders have the desired characteristics.
